The World's Carbon and Graphite Source The World’s Carbon and Graphite Source THE WORLDWIDE SUPPLIER OF CHOICE FOR REFINED GRAPHITE AND OTHER CARBONS CARBONS ARE ASBURY Carbon Is Life. Amorphous carbons such as coal, petroleum coke, pitch coke, active carbon and carbon black have unique physical and chemical properties. These properties Carbon is the basic enable us to process amorphous carbons into a myriad of industrial products including chemical-reducing agents, carbide-forming reagents, metallurgical building block of all products, cathodic protection materials and absorbing carbons, just to name a few. organic substances and is Carbon in the form of crystalline graphite possesses a combination of properties therefore the basis of all including lubricity, refractoriness, chemical inertness, as well as thermal and electrical conductivity. These properties make graphite the material of choice living things. Because for thousands of end-use applications, including friction materials, crucibles, refractories, cements, lubricants, chemical tank linings, powder metal parts, carbon combines readily polymer compounds, drilling fluids, electric motor brushes, batteries and artificial diamonds, fuel cells, fire retardants, gaskets and seals as well as with oxygen, giving off cathodic protection, among many others. heat as a by-product, it is also a vital energy source.

It is called “amorphous” because to the naked eye, macroscopic graphite crystals are not visible. This form of graphite has Asbury Carbons, the an “amorphous” appearance. world’s largest Carbon content: 70 – 88% Particle sizes: 5" – 1µm independent processor and merchant of graphite, Flake graphite is a naturally occurring form of graphite. Its properties include is a major supplier of high thermal and electric conductivity, and low spring-back (excellent molding natural and synthetic characteristics). Flake graphite is used in many applications including powder metallurgy, fuel cell bipolar plates, coatings, thermal materials, friction moderators, graphites, related carbon electrically conductive materials, refractories, general lubricant applications, pencils, gaskets, rubber compounds and other advanced polymer systems. products, and a variety of Carbon content: 70 – 99.9% other raw materials used Particle sizes: 20 mesh – 1µm in a wide range of industries in America and Expandable flake graphite is an intercalation compound of graphite, which around the world. exfoliates when heated. This material is manufactured by treating flake graphite with various intercalation reagents. These reagents migrate between the graphene layers of a graphite crystal and remain as stable species. If exposed to a rapid increase in temperature, the decomposition of the intercalants develops enough force to push apart the graphene layers resulting in an increase in the volume of the graphite of up to 300 times, a lowering of bulk density and approximately a 10-fold increase in surface area. Carbon content: 85 – 99% Expansion ratio: 70 – 300 ml/g pH: 2 – 8 Vein graphite is a naturally occurring pyrolytic carbon. This form of graphite is believed to be deposited as solid graphite directly from a fluid phase, creating an extremely high degree of crystallinity. Vein graphite is utilized extensively in formed graphite products for electrical applications. High-quality electrical motor brushes and other current-carrying carbons are based on formulations using vein graphite. It is also used in friction applications, such as advanced brake and clutch formulations, as well as most applications that utilize flake graphite. Carbon content: 80 – 99% Particle sizes: 2" – 1µm SYNTHETIC GRAPHITE Synthetic graphite is a manufactured product made by the high-temperature treatment of certain amorphous carbon materials. Ultra-high processing temperatures ensure purity higher than 99 percent. Synthetic graphite is used in many applications including friction, foundry, electrical carbons, fuel cell bipolar plates, coatings, electrolytic processes, corrosion products, conductive fillers, rubber and plastic compounds, and drilling. It is available in primary, secondary and purified forms. Carbon content: 98 – 99.9% Particle sizes: 3/8" – 1µm Graphco is a unique continuous graphitized material manufactured using a proprietary thermal process. It is made from only the highest quality petroleum coke, thermally engineered to provide a consistent, high-purity product. Graphco offers the benefits of conventional synthetic graphite such as high electrical and thermal conductivity, and low ash and sulfur content. The Graphco manufacturing process results in semi-graphite with high compressibility, which is effective in products and processes that require a powder or granular graphite with high spring-back. Carbon content: 98 – 99.9% Particle sizes: 3/8" – 1µm PELLETIZED CARBONS Asbury offers graphite pellets that are made from high-quality synthetic or flake graphite fines. Blended graphite pellets are also available. These pellets have proven to be very effective as carbon raisers, trim carbon and cover carbon in the hot metals industry. All pellets are manufactured with a proprietary binder that imparts rigidity and toughness to the pellet. Graphite pellets are much cleaner to handle than other carbon products. SURFACE ENHANCED FLAKE GRAPHITE Surface enhanced flake graphite(SEFG) is a form of natural flake graphite, processed using a proprietary combination of chemical treatment and mechanical milling. This processing results in a morphology that enhances graphite’s suitability in applications such as heat transfer materials and solid and fluid phase lubrication. SEFG has about twice the surface area expected for similarly sized conventional flake graphite.

This section is not mandatory. Abstract: The Madzaringwe Formation in the Vele colliery is one of the coal-bearing Late Palaeozoic units of the Karoo Supergroup, consisting of shale with thin coal seams and sandstones. Maceral group analysis was conducted on seven representative coal samples collected from three existing boreholes—OV125149, OV125156, and OV125160—in the Vele colliery to determine the coal rank and other intrinsic characteristics of the coal. The petrographic characterization revealed that vitrinite is the dominant maceral group in the coals, representing up to 81–92 vol.% (mmf) of the total sample. Collotellinite is the dominant vitrinite maceral, with a total count varying between 52.4 vol.% (mmf) and 74.9 vol.% (mmf), followed by corpogelinite, collodetrinite, tellinite, and pseudovitrinite with a Citation: Denge, E.; Baiyegunhi, C. count ranging between 0.8 and 19.4 vol.% (mmf), 1.5 and 17.5 vol.% (mmf), 0.8 and 6.5 vol.% (mmf) Maceral Types and Quality of Coal in the Tuli Coalfield: A Case Study of and 0.3 and 5.9 vol.% (mmf), respectively.

  • Anthracite Anthracite – an Overview
    ANTHRACITE ANTHRACITE – AN OVERVIEW Anthracite is a high-rank coal, representing a coal that has been subjected to the highest grade of metamorphism. Anthracite is shiny black, hard and brittle and has the highest fixed-carbon content. Due to its low volatile matter, anthracite's combustion process is slow. Most anthracites have low-moisture content and their heating value is up to 8,200 kcal/kg. Anthracite combusts with hot, clean flame, containing low content of sulfur and volatiles. Due to these characteristics, anthracite is often used in specialized industrial uses that require smokeless fuels. 2 CLASSIFICATION OF COAL 3 ANTHRACITE – AN OVERVIEW Anthracite has a history of use A small amount of impurities in blast furnaces for iron smelting; and a high percentage of carbon however, it lacks the pore space of makes anthracite coal the most metallurgical coke, which advantageous for combustion, as eventually replaced anthracite. it gives the maximum amount of Nonetheless, anthracite is a unique energy. high-tech raw material characterized by the maximum carbon content.

The Pennsylvania Anthracite District – a Frontier Area for the Development of 1 Coalbed Methane? By Robert C. Milici2 Abstract3 The anthracite region of eastern Pennsylvania consists of four major coal fields that are within the folded and faulted Appalachians, in the Valley and Ridge and Appalachian Plateaus physiographic provinces. These are, from south to north, the Southern Anthracite field, the Western Middle Anthracite field, the Eastern Middle Anthracite field, and the Northern Anthracite field. Rank of the coal ranges from semi-anthracite to anthracite. In general, the anthracite fields consist of Pennsylvanian strata that are complexly folded, faulted, and preserved in structural synclines within older Paleozoic strata. Published gas-in-place (GIP) data for Pennsylvania anthracite range from 6.4 SCF/ton (0.2 cc/g) for the Orchard coal bed to a high of 691.2 SCF/ton (21.6 cc/g) from a sample of the Peach Mountain coal bed that was collected in the Southern Anthracite field at a depth of 685 feet. This is the largest GIP value that the U.S. Bureau of Mines (USBM) (Diamond et al, 1986) reported for coalbed methane (CBM) nationwide. Of the 11 CBM analyses reported for the Southern Field by USBM, seven exceed 396 SCF/ton (12.4 cc/g) (average of 11 samples: 325.8 SCF/ton [10.2 cc/g]).
